Abstract

PURPOSE:To reduce the chip area and power consumption, by using a data selector circuit to connect write-in and readout data to the selected data bus. CONSTITUTION:When select line Y1 is selected by Y decoder 4, digit lines D1 and D2 are connected to a pair of data busses RB1 and RB2 simultaneously. Respective busses RB are connected to data selector circuit 15, and circuit 15 outputs only information of one data bus line, which is selected by Y decoder 14, through amplifier 21. For write, data is supplied to circuit 15 through amplifier 20, and the data bus line where data should be written is selected by Y decoder 14, and data is transferred and is transferred to only one digit line selected by decoder 4, thus writing in.
